What is semispinalis cervicis?
Semispinalis Cervicis belongs to the Transversospinal group of muscles, formed of muscles between a spinous process and the transverse process of the vertebrae below . Transverse processes of T1 to T6, articular processes of the 4th to 7th cervical vertebrae
How many fascicles does the semispinalis have?
These muscles are divided regionally into the semispinalis capitis, cervicis and thoracis. Semispinalis thoracis consists of five fascicles bridging over five to six vertebral levels between the transverse and spinous processes of certain cervical and thoracic vertebrae.
Is the semispinalis capitis a muscle?
Semispinalis capitis muscle (Musculus semispinalis capitis) Semispinalis capitis is a long paired muscle that belongs to the deep layer of muscles of the back. It forms the superior, and largest, component of the three-part semispinalis muscle.
What is the function of semispinalis thoracis?
Semispinalis thoracis consists of five fascicles bridging over five to six vertebral levels between the transverse and spinous processes of certain cervical and thoracic vertebrae. With these attachments, semispinalis thoracis aids several movements of the vertebral column; specifically extension, lateral flexion and rotation of the thoracic spine.
What is spondiloza cervicala?
Spondiloza cervicala este cel mai des intalnita la persoanele cu varsta mai mare de 40 de ani, in special in cazul celor sedentare si supraponderale. Spondiloza este denumirea generala care se refera la degenerarea coloanei vertebrale, indiferent de cauzele care au dus la aceasta.
What is the endocervical canal?
The endocervix, or endocervical canal, is a tunnel through the cervix, from the external os into the uterus. The overlapping border between the endocervix and ectocervix is called the transformation zone. The cervix produces cervical mucus that changes in consistency during the menstrual cycle to prevent or promote pregnancy.
What are the anatomical features of the semispinalis muscle?
The main anatomical feature of the semispinalis muscle, and of the semispinalis cervicis, is that it attaches between the spinous and transverse processes of vertebrae, bridging five to six vertebral levels along its course. Semispinalis cervicis acts in synergy with its capitis and thoracis counterparts.
